Specification of'Letters Patent.

Patented June 23, 1914.

Application filed March 10, 1913. Serial No. 753,236.

T o all whom t may concern.'

Be it known that I, JOHN D. ADAMI, a citizen .of the United States, residing at Kansas City, in the county'of Jackson and State of Missouri, have invented a certain' new and useful Improvement in Stack Razin and Conveying Mechanisms, of `which the following is a specification.

My invention relates to improvements in stack razing and conveying mechanisms.

It is adapted for razing and conveying stacks of grain, straw or hay.

It is articularly adapted for use in taking hea ed rain from a. stack and feeding it to a thresliing machine.

It is also adapted to take grain from two stacks simultaneously and feed it to a threshing machine.

Other novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings which illustrate the preferred embodiment of my invention, Figure 1 is a front elevation of the machine, shown located in operative position between two straw stacks. Fig. 2 is a plan view of the machine, some of the parts being omitted so as to more clearly show the remaining parts. Fig. 3 is a vertical section on the plane of the line a-b of Fig. 2.

Fig. 4 is a horizontal sectional view on the line o--d of Fig. 3. Fig. 5 is a vertical sectional view showing a portion of the supporting frame and the ratchet mechanisms.

Similar characters of reference designate different parts inthe diiferent views.

The machine is provided with a supporting fra-me comprising two horizontal beams 1, one set of ends of which are supported by standards 2, in which is mounted an axle 3,

having carrying wheels 4 mounted thereon, as is best shown in Fig. 3. The other set of ends of the beams 1 are supported on a bolster 5, pivotally mounted on a bearing 6, by means of a king. 'bolt 7. Mounted in the bearing 6 is'the front axle 8, on which are mounted carrying wheels 9, as is best shown in Fig. 1. f

From the bea-ms 1, upwardly extend standards 10, having secured to their ,upper ends brackets 11. The standards 10 have secured to them horizontal beams 12. Above the beams 12 and also secured in a horizontal position to the` standards 10, are bars 13.

Upon opposite sides' of the supporting frame are mounted two sets of reciprocatve rakes which are adapted to engage and remove straw from two stacks A and B, between which the machineois located, as is shown lin Fig. 1. Each beam 12, adjacent to its opposite ends, is provided with two longitudinal slots 14, in which are slidably mounted respectively, two longitudinal bars 15, which respectively support the two sets of rakes, above referred to. The rakes of each set are of the usual hand rake form and are provided with teeth 16 and transversely extending curved handles 17. The handles 17, as is best shown in Fig. 2, are preferably ofdiiferent lengths, whereby the teeth of some of the rakes will be in advance of the teeth of the other rakes. The inner ends of the handles 17 are provided with bearing portions 18 which are pivotally mountedI upon the adjacent bar 15.

For reciprocating the bars 15 in the slots 14 each bar 15 has pivoted to it one set of ends of a plurality 0f links 19, the other set of ends of which are respectively pivoted to crank pins 20, mounted on disks 21, which are secured to longitudinal shafts 22, mounted in the supporting framework, as is best shown in Fig. 4.

Respectively. secured to the shafts 22 are spur gear wheels 23, which respectively mesh with spur gear wheels 24, which are `secured to longitudinal shafts 25, which are mounted in the standards 10. Secured respectively to the shafts 25 are bevel gear wheels 26 whichk mesh respectively with bevel gear wheels 27, which are secured to a horizontal shaft 28, mounted rotatively in bearings 29, which are respectively support- Yed by the beams 1. Secured to the shaft 28 is a driving pulley 30, which maybe driven by any desired mechanism, not shown. For guiding the handles 17 of the rakes and for vertically adjust-ing the same, to suit the height of the stack upon which the machine is operating, the following described mechanism is provided t-Two longitudinal shafts 31, which are provided at one set of ends with hand wheels 32, have respectively mounted uponI them, in a pivotal manner, two sets of transversely extending bars 33, each set ofwhich carries two longitudinal bars 34, andi 35, on which are respectively pivotally mounted two sets of bellcrank levers 36 and 37. One setof ends of the bell crank levers 36, are pivotally connected to one set of ends respectively of links 38,

the other set of ends of which are respectively connected to crank arms 39, which are secured to the adjacent shaft 31. By turning the hand wheels 32- the cranks 39 will swing the bell crank levers 36. In the other set of ends of each set of bell crank levers 36, is mounted a longitudinal bar 40, upon which are mounted guide lmembers 41 through which extend respectively and in which are slidably mounted, the two shorter sets of rake handles 17 as is best shown in Figs. 2 and 3. In a similar manner, links 42, respectively connect one set ofends of the bell crank levers 37 with crank arms 43, which are secured to two longitudinal shafts 44, which are rotatively mounted in the bars 13 of the supporting frame. The two bars 44 have respectively securedto them hand wheels 45 by whiclrthe shafts may be turned for the purpose of swinging the bell crank levers 37. In the outer ends of each set of bell crank levers 37, is mounted a longitudinal bar 46, carryingl guide members 47, having eyes in which are slidably mounted and guided the two longer sets of handles 17, of each set of rakes.

From the foregoing it will be seen that by manipulating the hand wheels 32 and 45 the bell crank levers 36 and 37 may be independently swung so as to adjust the rakes having the longest and next longest handles independently of t-he other rakes.

In order that both sets of rakes at each side of the machine may be simultaneously raised or lowered as the work requires, mechanism is provided for vertically swinging the bars 33, which support the bell crank levers 36 and 37. This mechanism consists in the following parts z-Referring to Figs. 3 and 5, 48 designates two longitudinal shafts which are rotatively mounted in bearf ings 49, which are supported by the standards 10. As shown in Fig. 2, and also in Fig. 1, one set of ends of the shafts 48 are provided with hand wheels 50. Secured to one ofthe shafts 48 are crank arms 51, which are pivotally connected to links 52. which in turn are pivoted to the inner ends of the set of bars '33, which are located at the opposite side of the machine. In a like manner', the other shaft 48 has secured to it similar crank arms 51, which are connected to links 52.

By turning the hand wheels 50 the bars 33 may be vertically swung so that their outer ends may move in a downward direction.- To swing the outer end of the bars' 33 upwardly I provide two sets of coilv springs 54, one set of ends of which are connected to the bars 35, and the other set of ends of which are connected to the brackets 11, as is best shown in i Figs. l and 3. In order to releasably lock the bars 33 from being drawn upwardly. by

springs 54, the shafts 48 have respectivelyl secured to them ratchet wheels 55 which are engaged respectively by pawls 56, as is shown in Fig. 5. Similarly, shafts 31 have secured to them respectively ratchet Wheels 57, which engage with pawls 58 respectively, said pawls being pivoted on the standards 10. In a like manner, shafts 44 have respectively secured to them ratchet wheels 59, which are respectively engaged by pawls 60. The pawls 56 and 60 are pivotally mounted on one of the bars 13, as shown in Fig. 5. The pawls 58 and 60 prevent the weight of the rakes` on the bell cranks 36 and 37 from swinging the outer ends of said .bell cranks downwardlyvu'nless the pawls are released from the ra-tchets with which they are engaged.

When the driving pulley 30 is rotated, the rake handles 17 at each side ofthe machine, will be moved inwardly and outwardly in sol dles having a camber, the movement of the handles throughthe guides will cause them to have a clawing movement similar to the movement imparted to a hand rake by one who is raking hay. By arranging the rakes at each side of the machine, one in advance of the other, theouter rakes will, upon their I, inward movement, draw a certain portion of the material a predetermined distance,- which portion will, upon the next inward movement of the rakes, be engaged and drawn still farther toward the machine and to a position in which it will be engaged by the adjacent inner set of rakes upon the next succeeding inward movement thereof. In this wa y the material forming the stack will be drawn from the top of the stack to the side of the stack next to the machine where it will fall upon a conveying mechanism with which the machine is provided and by such conveying mechanism carried tothe plae at which the material is to be delivere I will now describe the conveying mechanism just referred to.

Pivoted at theirupper ends to each shaft 25, as shown in Figs. 3 and 4,are downwardly inclined bars 61, in the lower ends of which are mounted longitudinal shafts 62, to which are secured rollers 63, which engage and drive upwardly and inwardly inclined belt conveyers 64, the upper ends of which are mounted on rollers 65, which are mounted on the shafts 25, and serve to'drive the belt conveyers 64.. y

The belt conveyers 64 are driven'in a direc-tion such that their upper sides will move upwardly and discharge' the material, which has been raked' from the stacks and dischargedy thereon, upon a longitudinal belt conveyer 66, .which is disposed between the standards 10, and which is mounted upon two rollers 67 and` 68, rota-tively supported, in a horizontal transverse position, by and between the beams 1. The belt conveyer 66, is driven by the roller 67, which has secured to it, as shown in Fig. 3, and in Fig. 4, a pulley wheel 69, which is driven by means of a belt 70, which is also mounted on a pulley wheel 71, which is secured to a sprocket wheel 72, mounted on a lateral stud 73, extending outwardly from one of the st-andards 29. A sprocket chain 74, connects the sprocket wheel 7 2 with a sprocket wheel which is secured to the driving shaft 28, as is best shown in Figs. 1 and 4. Blocks 76, are pivotally mounted to the shafts 62, and serve to support the lower ends of the lateral conveyers, as is shown in Figs. 1 and 3.

When the machine is to operate upon two stacks simultaneously, it is wheeled into the position shown in Fig. 1, after which the blocks 76 are permitted to rest upon the ground and the hand wheels 32. 45 and 50 are then adjusted so as to properly position the rake teeth 16, relative to the top of the stacks A and B. The shaft 28 is then driven, thereby effecting the reciproca-ting, clawing action of the rakes and the driving of the belt conveyers 64 and 66, by means of the mechanism which I have already described. The material .forming the stack will be raked therefrom and deposited upon the belt conveyers 64, which in turn will deposit the material upon the belt conveyer 66, from which conveyer the -material will be delivered to a threshing machine or to such place as it'- may be desired to deliver it.

As the stacks are lowered the bars 33 are swung downwardly at their outer ends by a proper manipulation of the 'hand wheels 48. As occasion requires, the hand wheels 32 and 35 may be adjusted so as to vary the relative positions of the rakes.

I do not limit my invention to the struc ture shown and described, as'modifications, within the scope ofthe appended claims, may be made without departing from the spirit of my invention.- i

Having thus described my invention, what I claim and desire to secure by Letters Patent is v 1.
